Answer and Step-by-step explanation:
When multiplying exponents:
- Product of Powers: When the base of the exponents are the same, and the bases are being multiplied to each other, the exponents are added together.
- Different bases Same Exponents: When the bases of the exponents are different, but the exponents are the same, the bases multiply together (within a parenthesis) with the exponent on the parenthesis.
- Quotient of Powers: When the base of the exponents are the same, and they are being divided by each other, the exponents will subtract from each other.
- Power of a Power: When a base has an exponent, and that entire term has and exponent, the exponents multiply together.
- Power of a Product: The opposite of Different bases Same Exponents. Distribute the exponent onto the different bases.
- Power of a Quotient: The opposite of Quotient of Powers. Distribute the exponent to the dividing bases.
- Zero Power: Any number raised to the 0 power equals 1.
- Negative Exponent: Any number raised by a negative number goes to the denominator of a fraction (if not already in the denominator), and vise versa (goes to the numerator if not already in the numerator).
- Power of One: Any number raised to the power of 1 is the same number.
